From: dropzone20 | #001 In the captivate trailer 1:40 mark Sherry gets backhanded in slow-mo by the Drill-hand Tyrant but she's perfectly fine in the China segment with no visible injuries.
Did the G anti-bodies in Sherry's system give her regenerative abilities?
Did you see the ridiculous spinal smashing Chris took from his squadmate-turned-monster? And he's totally mobile in the China part too. The point is, most potentially life threatening injuries RE characters endure are in fact not particularly life threatening.
